The first person credited with measuring the Earth's circumference was the ancient Greek mathematician and astronomer Eratosthenes. He used the angle of the shadow cast by a vertical stick in Syene and Alexandria to estimate the Earth's size with impressive accuracy for his time.
In Christian tradition, the first person on Earth was named Adam. According to the Bible, Adam was the first man created by God.
The first person credited with accurately calculating the Earth's circumference was the ancient Greek mathematician and astronomer Eratosthenes in the 3rd century BC. He did so by measuring the angle of the sun's rays at two different locations and using simple geometry to estimate the Earth's size.
Eratosthenes of Cyrene (276 BC - 194 BC) was a Greek mathematician, poet, athlete, geographer and astronomer. He made several remarkable discoveries and inventions: he devised a system of latitude and longitude. He was the first person to calculate the circumference of the Earth with remarkable accuracy, and the tilt of the earth's axis.
The first layer of the Earth's atmosphere is called the troposphere, and it is in direct contact with the Earth's surface. This layer is where weather events occur and where most of the Earth's clouds and precipitation are found. Temperature usually decreases with altitude in the troposphere.
According to various religious texts, Adam and Eve are considered the first human beings created by God on Earth.
False. He is the first known person to calculate the circumference of the earth. Wikipedia has more information in their post on this interesting fellow. A link to the post is provided below.

In Christian tradition, the first person on Earth was named Adam. According to the Bible, Adam was the first man created by God.
He invented the system of longitude and latitude.He was too the first person who calculate the circumference of the Earth.
Eratosthenes had many contributions : he was the first person to calculate the circumference of the earth he invented latitude and longitude he was the first person to prove earth was round he was the first to calculate the tilt of Earth's axis

erathosthenes was the first ,
One possible person is Eratosthenes of Cyrene ~230 BC as he was a Greek scientist who calculated the circumference of the Earth, with remarkable accuracy (some values for the "stadia" he used gives a result within 6% of the actual polar circumference). See link for further information
The Greek mathematician and astronomer Eratosthenes is credited with calculating the Earth's circumference around 240 B.C. using the angle of the sun's rays at two different locations and the distance between those locations. This method provided a reasonably accurate estimate of the Earth's size.
To get the diameter from the circumference of a circle, just divide by pi (which is 3.1415 to the first 5 digits).
If you mean a circle, first find out the radius (circumference = 2 x pi x radius, so you divide the circumference by 2 and by pi).
First, mesure your door, then find out a screen door as close your mesurement.. Then screw it on the surface.
